, SPECIFICATION forming part of Letters Patent No, 420,662, datedFebruary 4, 1890. Application filed March 2,1887. sale to. 229,441. (Nomodel.)

To all whom it may concern.-

Be it known that I, GEORGE JOHNSTON, of Detroit, county of Wayne, Stateof Michigan, have invented a new and useful Improvement inEyeglass-Frames; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form a part ofthis specification.

The object of my invention is to provide improved eyeglass-frames soconstructed that the nose guards may offset from the plane of theglass-frames toward the eye of the wearer, to permit the glasses beingmore satisfactorily located upon the nose. By making the noseguards tooffset toward the eye they may set farther back upon the nose, and underthe eyebrows if necessary, to give the glasses a firmer grip upon thenose and to permit their adjustment in a more efficient and agreeablemanner.

I carry out my invention as follows:

In the drawings, Figure 1 is a perspective View illustrating myinvention, showing the extremities of the nose-guards slotted to receivea horizontal tongue on the arm. Fig. 2 is a similar view illustrating amodification thereof, wherein the horizontal arm is slotted to receive atongue 011 the nose-guards. Fig. 3 is a modification showing the offsetarm 7 provided witha vertical slotted shoulder to engage a tongue on thenose-guard, and Fig. 4. a similar view showing the offset arm providedwith a vertical tongue to engage a slot in the noseguard. Fig. 5illustrates the method of engaging the angular arms upon theirrespective posts.

A A represent the glass-frames.

13 represents the ordinary spring connect-- ing the said glass-framesthrough intermediate posts a a, or otherwise, in any desired manner.

0 0 represent the guards by which the glasses are held upon the nose.Said noseguards may be connected at their base in any suitable mannerwith the glass-frames, preferably by intervening lugs A A which may beset at an angle to the plane of the glass frames.

' their respective posts aa.

D D represent angular offset arms engaged at one end upon theconnecting-posts a a,

and at the other ends, which offset from the plane of the glasses, saidarms are adj ustably engaged with the upper extremities of saidnose-guards, respectively. These offset arms D D, are each constructedwith an arm d, projecting in a line with the ends of theconnecting-spring B and lap past the ends of said springs and areengaged therewith on These posts are preferably constructed with flangedsides, as shown in Fig. 5 at b b, projecting upward to embrace theadjacent sides of the spring and the shoulders of said arms, therebypreventing the arms from turning in a horizontal plane on theirengagement with the post. The up per ends of said nose-guards C C arebent in suitable form toward their respective glassframes, to afiordconnection with the offset ends of said arms D D. The inner or offsetends of said arms may terminate in a hori= zontal arm d, which, as inFig. 1, may be constructed in the form of a T-headed tongue, theadjacent extremity of the guard being slotted to receive said tongue; orsaid hori* zontal arm d may be constructed with an elongated slot, asshown at (1 and the adjacent end of the nose guard be provided with aT-headed tongue to engage in said slot. So, also, as shown in Figs. 3and 4, the arms may terminate in vertical flanges d said flanges beingeither constructed with a T-headed tongue to engage a slot in theadjacent end of the nose-guard, as shown in Fig. 4, or said flange maybe provided with a slot, the adja* cent end of said nose-guard beingconstructed with a T=headed tongue toengage said slot, as shown in Fig.3, thereby permitting an automatic adjustment of the nose-guards to andfro.

It is immaterial, so far as the scope of this present invention isconcerned, whether the extremity of the nose-guards be slotted and theadjacent arms be tongued therein, or vice versa, it only being necessarythat either the one or the other should be tongued and the otherslotted. The angular extremity of said arm may project vertically fromthe offset portion of the arm in a vertical direction, either upward ordownward, as may be preferred.

WVhat I claim is 1. The combination, with an eyeglass-frame and anose-guard, of a fixed offset piece, consisting of a single piecesecured to the eyeglass-frame at one end, its other end having aself-adjusting connection with the noseuard, substantially as hereindescribed.

2. The combination, with the glass-frames, of a connecting-spring,noseguards engaged at the base with said glass-frames, and rigid angulararms offset from the plane of the glass-frames and provided withverticallyextended arms having a slot and-tongue engagement with theupper extremities of said noseguards, whereby said guards will beantomatically adjustable, substantially as described; v

3. The combination, with eyegiasaframes, of a connecting-spring;noseguards engaged at the base with said frames, and rigid angular armsoifset from the plane of the glassframs, having a slotand-tong'ueengagement with the upper extremities (if said guards, whereby the upperends of said nose-guards will offset from the plane of the glass-framesand be automatically adjustable upon said frames, substantially asdescribed.

4. The combination, with the eyeglassframes, of a connecting-spring,nose-guards engaged at the base with lugs or said glassframes, andangular arms offset from the plane of the glass-frames and engagedtherewith by intervening posts a a, said arms and said guards having aslot-and-tongue engagement, said posts flanged at their upper ends toengage the edges of said arms, substantially as and for the purposesdescribed.

5. The combination, with the eyeglassframes and their connecting-spring,of rigid oifset arms and nose-guards engaged at one end upon said framesand at the other end having a self-adjusting engagement with said oifsetarms, substantially as deseribed;

In testimony whereof I sign this specificaticn in the presence of twowitnesses.
